Appraisers say future home valuations of the neighborhood should reflect the risk of more sinkholes.

"I would definitely disclose (this history) in the appraisal," said Patricia Staebler, a licensed appraiser in Bradenton, speaking on background. "It (depends) on the size of the sinkhole, the severity of the sinkhole, and sinkhole patterns in the area."

Staebler couldn't put a percentage on the value drop, but said the entire Seffner/Plant City area could face the stigma that comes with several years of off-and-on sinkhole problems.
